Bodycon Dress

1. **Square Neckline**: A square neckline offers a structured and elegant look. It frames the neck and collarbone nicely, giving the dress a refined and timeless appearance.

2. **Sweetheart Neckline**: This adds a soft, romantic touch to the bodycon dress while accentuating the bust area. It's flattering and feminine without being overly revealing.

3. **V-Neck**: A classic V-neck elongates the neck and gives a flattering silhouette. It adds a sleek and stylish vibe to a bodycon dress, perfect for both casual and formal settings.

4. **High Neck/Turtleneck**: This gives the dress a chic and sophisticated look, perfect for a more formal or professional vibe. It’s simple yet stunning, adding elegance to the overall style.

5. **Keyhole Neckline**: A keyhole design adds a subtle yet alluring detail to the front, giving the dress a unique and fashionable touch without being too revealing.

6. **Boat Neck**: A boat neckline provides a modest and graceful look, skimming just along the collarbone. It’s perfect for a sleek and understated appearance.

These neck designs will make a grey bodycon dress look stunning while maintaining a refined and stylish edge without the off-shoulder style.
